Excuse me, I meant that I had 1.4.3 hotfix, not 1.4.2. My friend won't be online for some time, but when he does come online and try to fix it I'll inform if it worked or not. Thanks for the help guys. :D
So basically, I have downloaded the launcher version of MBII, and my friend has downloaded the archive version. He is stuck on version 1.3.2, while I'm on 1.4.2. Both of our launchers say hotfix 1.4.2 yet he has an outdated version of the game and his launcher does not notify him for an update...
